NEW Kasco’s Robust-Aire™ systems are NOW 34% quieter and easier to maintain. Newly redesigned, these systems feature a significant reduction in sound (patent pending), larger air filters on 1/4HP and 1/2HP systems for less frequent cleaning, and a visual maintenance indicator to alert when maintenance is needed.

Robust-Aire™ systems pump compressed air from a shore-mounted compressor through self-weighted lines to a diffuser on the pond, lake or tank bottom. The diffuser then continuously releases micro-bubbles that rise to the surface carrying large volumes of water. This induces oxygen-transfer as well as beneficial water movement and mixing.

All Robust-Aire™ diffused aeration systems are available with an optional remote manifold allowing the compressor to be installed up to a mile away from the water’s edge.
